The main food of crabs is small fish, shrimp, seaweed, etc. Crabs spend most of their time looking for food, they are generally not picky eaters, as long as the chela can get their hands on food, small fish and shrimp are their favorite, but some crabs eat seaweed, and even animal carcasses and plants can eat. Crabs eat other animals, and other animals may also eat crabs, for example, humans use crabs as a delicacy, and water birds also eat crabs, and some fish also like humans to eat crab legs.
When young and juvenile crabs float in the sea in groups, they may be preyed upon by other marine organisms, so crabs have to lay a lot of eggs when laying eggs to ensure the survival rate of crabs. Extended Information: Morphological Characteristics of CrabsAlthough crabs are small, they are complete.
When the hard shell of the crab is removed, we can find that the crab's body parts are protected by a layer of shells, shield-like shells that biologists call carapace. The body of the crab is symmetrical and can be divided into frontal area, eye area, heart area, liver area, stomach area, intestinal area, and gill area. The two sides of the crab's body are connected by appendages.
Appendages on the head, called antennae, have the sense of touch and smell, and some appendages have the function of mouths, which are used to tear food and put it in the mouth. The crab thoracic cavity has five pairs of appendages called thoracopods. Based on the fact that the two feet at the tail end of the crab are less involved in walking, a six-legged lateral moving walking mechanism was developed by imitating the walking style of the crab, and its movement characteristics were studied to meet the requirements of traveling on rigid ground and soft ground involved in agricultural production.
